Perusal of records concerning 14 patients diagnosed and operated for Cysts of the thyrolingual duct, in the last 5 years (1984-1989). In this term the AA. have had at their disposal the newly diagnostic methods introduced at their Hospital. Among the clinic features considered in the paper, for instance, the age, they…

The reproductive rates of about 50 species of Australian rodents were studied by calculating allometric equations for the relationships between female body weight, litter size, length of gestation and weaning periods as well as age of sexual maturity.Members of the subfamily Hydromyinae, which invaded Australia 5-10 mi…

The authors present the results of an inquiry conducted in the principal hospitals of Algeria. The number of cases of visceral leishmaniasis recorded over the last ten years (1965 to 1974) totaled 497. The disease occurs essentially in children under 5 years of age (94%); it is mainly detected in central and eastern pa…

Interleukin-5 (IL-5) exerts a central pathogenic role in differentiation, recruitment, survival, and degranulation of eosinophils. Indeed, during the last years, significant advances have been made in our understanding of the cellular and molecular mechanisms underlying the powerful actions of IL-5 finalized to the ind…

The relative contributions of decreased upstream sediment loads and local estuarine engineering activities to the estuarine channel geometry are poorly understood. In this study, we analyze the hydrological changes and identify the location, duration and intensity of the estuarine engineering activities based on the ch…

Visual snow is a persistent visual disturbance in which small dots of light appear across the visual field of both eyes, like snowfall. The condition is not widely known, but an increasing number of cases have been described in the last 5 - 6 years. Many patients have consulted a number of specialists without…

•More than 70% of all deaths in the BRICS countries are attributable to noncommunicable diseases.•There have been marked changes in physical activity levels, time use, and energy expenditure in these nations over the last 20 years.•There are marked gender differences in physical activity in 4 of th…

Applications of conducting polymers to biosensors have recently aroused much interest. This is because these molecular electronic materials offer control of different parameters such as polymer layer thickness, electrical properties and bio-reagent loading, etc. Moreover, conducting polymer based biosensors are likely…

Heart failure is a common clinical problem, affecting at least 5 million Americans. There have been substantial advances in the understanding and treatment of heart failure in the last several years. We review current concepts for the evaluation and treatment of the various manifestations of patients with heart failure…

The authors presented 6 cases of malignant neoplasms of intestine. Five of them were undergone emergency surgery, while one elective, due to complaints notified previously for a longer time. In all cases a segmental resection of intestine was done. Two patients were complementarily treated using chemiotherapeutics. Thr…

In the last 5 years we have performed 14 phase I studies in our department. Eight of these trials involved evaluation of both the clinical and the pharmacokinetic behaviour of novel anti-cancer agents. The remainder investigated various aspects of drug delivery, targetting or resistance modification with existing anti-…

A case of massive chronic fetomaternal transfusion with a loss of 500 ml blood is reported. A review of 24 cases covering the last 10 years shows that chronic fetomaternal transfusions do not lead to intrauterine dystrophy. During birth there is a danger of acute decompensation, which led to an irreversible shock and d…

The benign systemic disorders with involvement of the spleen are divided into haematologic diseases, thesaurismosis, collagenosis, morbus Boeck, infectious diseases, parasitosis and others. 4/5 of the cases are haematologic diseases of the erythrocytic, the thrombocytic and lymphatic system as well as myeloproliferativ…

In the Department of Pediatric surgery, during the last ten years, 190 patients with supracondylar fractures (second and third degree, according to Bauman's classification) have been treated. The operation was performed in only 5% of all hospitalized cases. There were only one patient with neurological and vascular com…

Roentgenographic visualization of a calculus in the distal ureter is often made difficult by gas or bowel contents in the region of the pelvis. Filling the bladder with sterile water raises the bladder dome and displaces the bowel upward. Any calculus in the lower 4 to 5 cm. of the distal ureter is then clearly demonst…

Patients with early estrogen receptor-positive breast cancer are at continuous risk of relapse even after more than 10 years of follow up. Currently, no biomarker that identifies patients for earlylate recurrence, or one that selects patients or tumors for longershorter durations of endocrine therapy (ET) is available…

OBJECTIVE: Faith Moves Mountains assessed the effectiveness of a faith-placed lay health advisor (LHA) intervention to increase Papanicolaou (Pap) test use among middle-aged and older women in a region disproportionately affected by cervical cancer and low screening rates (regionally, only 68% screened in prior 3 years…

BACKGROUND: We examined deaths of Medicare beneficiaries in Massachusetts and California to evaluate the effect of managed care on the use of hospice and site of death and to determine how hospice affects the expenditures for the last year of life. METHODS: Medicare data for beneficiaries in Massachusetts (n = 37 933)…

The clinical and radiographic results of primary cemented total hip arthroplasty performed by a single surgeon, with particular emphasis on the performance of acetabular components implanted with so-called second-generation cement techniques, were studied. Seventy hips with 48 metal-backed and 22 polyethylene acetabula…
